i got the whole cluster replaced under extended warranty. its cost was around 10- 12000rs. few issues like boot not opening while engine is on, fuel gauge issue, starting trouble everything vanished once i changed the battery. --- Double Post Merged, Dec 19, 2015 --- no that include EGR and intake manifold cleaning only..anyway i haven't done that. got the car serviced.the whole experience with hyson motors was good. and their body wash needs a special mention here. it was top notch.
